Workers exposed to hazardous materials may be at risk for many serious health problems, such as kidney or lung damage, sterility, cancer, allergic reactions, or burns. Some hazardous materials can also cause fires or explosions. Legislation and regulations are in place to reduce injuries or diseases caused by exposure to hazardous materials used in the workplace. Every person working with or near controlled products has the right to know the hazards and how to safely use the products. The following list of lines and competencies was generated with the goal of creating an entry-level trades training resource, while still offering the flexibility for lines to be used as stand-alone books. Line A Books include: A-1 Control Workplace Hazards, A-2 Describe WorkSafeBC Regulations, A-3 Handle Hazardous Materials Safely, A-4 Describe Personal Safety Practices, A-5 Describe Fire Safety.
